Fortunatly to you, too many people have the same notion as you, about "soft meaning weaker technique". My understanding is quite to the contrary: soft should mean (among other things) full body utilization for a more effective technique, soft should also mean higher sensitivity enabling better control of damage (ibe soft and sensitive and you will feel his limitation, then in practice - slow down and in a real situation - use it to break him apart). But, as I worte, I am in the minority.

In any case, no one would be able to tell you how the new place will affect your shoulder, you may find Uke rolls more and it makes it impossible for you or vice versa.
